Thank you guys! Found the answer! Unisphere Central environment The Unisphere Central environment consists of a Unisphere Central server running in a VMware virtualized environment, one or more VNX, VNXe, and CX4 storage systems, and a computer running a supported browser to access the Unisphere Central application interface. Note: You can configure multiple instances of the Unisphere Central server in your environment but each server should monitor different storage systems. Do not monitor the same storage system with more than one instance of Unisphere Central. Cheers! Geraldo
Is it possible to add a VNX to two different Unisphere Centrals? If yes, any documentation to do it? Thank you! Geraldo!

Hi guys! I've been through with same problem with a customer here in Brazil...he followed all yours tips but in the last part " Now create a group, assign it a dataset and make the client part of that group.” Which client should I add to the group? Should I mount that CIFS server in a client that is in the VCenter and then add that client to the group? Hope you can help me! Cheers! Geraldo.

Hi there Can you copy/paste the cluster error here? If you an error similar to the one below, you can try: Error in the cluster log 00000a8c.00001530::2010/03/01-09:40:39.622 WARN  [RCM] ResourceControl(GET_CLASS_INFO) to Cluster Disk 4 returned 5038. 00000a8c.000015a0::2010/03/01-09:40:39.623 WARN  [RCM] ResourceControl(GET_RO_PRIVATE_PROPERTIES) to Cluster Disk 4 returned 5910 -Changed MPIO failover policy from Basic Failover to Round Robin or an Active/Active scenario (such as PowerPath default).    There is a performance issue with iSCSI in Microsoft Windows 2008 and later whereby the default TCP acknowledge time of the iSCSI Initiator is 200ms. A TCP packet from the node's iSCSI initator to storage may be delayed up to 200ms if the packet's payload does not fill an Ethernet sgement (based on the configured MSS) When using Microsoft's MPIO Round-Robin algorithm for iSCSI dealing with a larger number of Pass-through devices, the performance issue is exacerbated as there are now more iSCSI initiator paths to storage, reducing the given payload of the iSCSI CDB (SCSI OpCode). This problem does not appear as badly when using a single active path to storage. This problem is specific to iSCSI and does not exist in a Fibre Channel environment. This can affect the time taken to perform failure recovery, such as determining SCSI reservations when performing owner take-over (arbitration). Note: This is a Microsoft iSCSI Initiator problem and is not caused by any EMC software or EMC hardware.             You may advise the customer to open a Support Case with Microsoft Product Support Services. Note: This may negatively impact maximum network throughput (slightly - 1-2 % in testing) 1.  For each iSCSI Network Interface, follow Microsoft KB article KB 2020559  http://support.microsoft.com/?kbid=2020559 2.  Also, if the host is Windows 2008 R2 onwards, set the following parameter for improved send performance;    In the registry editor also create the following DWORD key and assign it a value of 1.                   HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E97B-E325-11CE-BFC1-08002BE10318}\<Instance Number>\Parameters\iSCSIDisableNagle                    Where <Instance Number> is the instance of your iSCSI Initiator. -This additional step shall be appended in the MSKB artcile 2020559 shortly. -Reboot after making the registry changes.

Hi there! Here is a info portion of the manual. You can find the whole manual in our powerlink.com Support > Technical Documentation and Advisories > Hardware/Platforms Documentation > VNX Series > Maintenance/Administration Select:  VNX Command Line Interface (CLI) Reference for Block  1.0 A02 Cheers! mirror -async -info Displays general information about asynchronous mirroring in a system. PREREQUISITES You must have a user account on the system on which you want to execute the command. DESCRIPTION This command, when used with naviseccli and no other switches, lists all general information for asynchronous mirror support. Issuing this command with one or more options displays the information based on the option issued. See the example for sample output. SYNTAX mirror -async -info [ -cancreate ] [ -maxmirrors ] [ -maxremoteimages ] [ -mirroredluns ] [ -mirrorableluns ] [ -systems [ -connectiontype ]] [ -all ] OPTIONS -cancreate Indicates whether an asynchronous mirror can be created in this system: yes or no. -maxmirrors Displays the maximum number of mirrors that can be created in this system. -maxremoteimages Specifies the maximum number of secondary images allowed. A maximum of one image is allowed. -mirroredluns Lists the LUN numbers of LUNs that are mirrored in this system. The list includes LUNs used as both secondary and primary images. -mirrorableluns Lists LUNs that can be mirrored in this system but are not mirrored at present. 752 EMC VNX Command Line Interface (CLI) Reference for Block EMC VNX MirrorView/A CLI -systems Lists remote systems that can be used for a secondary image. -connectiontype Displays the connection type (fibre or iSCSI) for the enabled mirror. For unexpected error cases, it displays the value, unknown. -all Lists all properties of a session without having to type in any other switch. EXAMPLE # 1 For SP ss1_spa , this command displays potential and current remote mirror information. naviseccli -h ss1_spa mirror -async -info Can a mirror be created on this system:YES Maximum number of remote images: 1 Logical Units that are mirrored in Primary Images:128 5 Logical Units that are mirrored in Secondary Images:0 Logical Units that can be mirrored:1 2 3 4 10 11 12 13 14 21 22 58 59 Remote systems that can be enabled for mirroring: Array UID: 50:06:01:60:90:20:27:47 Status: Enabled on both SPs Enabled Connection Type(s): iSCSI Disabled Connection Type(s): Fibre Maximum Number of possible Mirrors: 100 EXAMPLE # 2 The following example shows the output for the mirror -async -info command for the VNX5300 Block and VNX5500 Block systems. mirror –async –info –all mirror -async -list Displays information about existing asynchronous mirrors. PREREQUISITES You must have a user account on the system on which you want to execute the command. DESCRIPTION The naviseccli -async mirror command with -list and no other switches lists all information for all mirrors on the system. Issuing this command with one or more options displays the information based on the option(s) issued. You can direct the command to any system; however, only the system holding the primary image of a mirror will always have the latest information about the mirror. Status obtained from other systems may be stale; do not use it unless the primary system is unavailable. See the example for sample output. SYNTAX mirror -async -list [ -name [[ name ]] [ -mirroruid ] [ uid ] [ -description ] [ -faulted ] [ -images ] [ -imagecount ] [ -imagesize ] [ -lun ] [ -ownergroupuid ] [ -ownergroupname ] [ -requiredimages ] [ -state ] [ -timestamp ] [ -transition ] OPTIONS -name name Specifies the name you gave the mirror with the -create function. You can use the mirror name or unique ID to obtain information on a mirror. -mirroruid uid Specifies the unique 16-byte remote mirror ID (World Wide Name) the software assigned when it created the mirror. MirrorView/A remote mirroring commands 755 EMC VNX MirrorView/A CLI -description Lists the meaningful title for the mirror, if any. The software does not use the description to identify the mirror. -faulted Lists whether the remote mirror is faulted: yes or no. If it is faulted, the mirror is either fractured or in the attention state. -images Displays image information, such as the role of the image (primary or secondary), image ID, WWN of the LUN containing the image, recovery policy, sync rate, image state, image condition, and image transitioning. It also displays the update type (Manual, Time elapsed since the start of last update, and Time elapsed since the end of the last update), the update period in minutes (displays N/A where not applicable), the time in minutes since the last update, the time in minutes until the next update, the last image error (why the image is faulted; displays the Not Available if no error). -imagecount Lists the current number of images that compose the mirror. This count includes the primary image. -imagesize Lists the size of the image (capacity of the LUN containing the image) in user blocks. -lun Lists the LUN number of the local image. -ownergroupuid Lists the unique ID value of the consistency group of which the mirror is a member. -ownergroupname Lists the unique name of the consistency group of which the mirror is a member. -requiredimages Lists the minimum number of secondary images required for the mirror. -state Describes the operational state of the mirror. Values are: active and attention. -timestamp Returns the clock time when the last update started. 756 EMC VNX Command Line Interface (CLI) Reference for Block EMC VNX MirrorView/A CLI -transition Specifies whether the mirror is in a changing state. EXAMPLE naviseccli -h ss1_spa mirror -async -list MirrorView Name: pbc async ml 80 MirrorView Description: MirrorView UID: 54:33:20:90:60:01:06:50:03:00:00:00:00:00:00:00 Logical Unit Numbers: 80 Remote Mirror Status: Mirrored MirrorView State: Active MirrorView Faulted: NO MirrorView Transitioning: NO Minimum number of images required: 0 Image Size: 409600 Image Count: 2 Images: Image UID: 50:06:01:60:90:20:33:54 Is Image Primary: YES Logical Unit UID: 60:06:01:60:2F:E7:0C:00:3C:5B:04:A2:50:4C:D8:11 Image Condition: Unknown Image Condition Image UID: 50:06:01:60:90:20:29:85 Is Image Primary: NO Logical Unit UID: 60:06:01:60:3F:E1:0D:00:A4:C9:01:63:B6:4C:D8:11 Image State: Synchronized Image Condition: Normal Recovery Policy: Automatic Synchronization Rate: Medium Image Faulted: NO Image Transitioning: NO Synchronizing Progress(%): 0 Update Type: Manual Time in secs since previous update: 12550 Time in secs until next update: Not Available OUTPUT If the version of FLARE software running on the SP does not support this command, a Command is not supported error message is printed to stdout .

G'Day Ghuey Here are some information about LUN capacity for VNX 5300,VNX 5500, VNX 5700, VNX 7500. You can get more detailed information with "EMC Unified Storage Best Practices for Performance and Availability Common Platform and Block Storage 31.0" best practices. You can download it in our Powerlink. If you don't have a Powerlink account yet, let me know so I can send you via email. Maximum Virtual Provisioning LUN capacity  The capacity of the largest Virtual Provisioning pool LUN thick and thin for OE – Block 31.0 is 16 TB. Maximum traditional LUN capacity The capacity of the largest traditional LUN, is that of the largest, highest capacity drive RAID group.   A RAID group can be made-up of as many as 16 drives.  The data protection scheme, parity or mirror reduces the maximum capacity of the drives. For example, a 28 TB raw capacity LUN can be created using a 16-drive RAID-level 6 (14+2) dedicated group using 2 TB NL-SAS drives. Maximum MetaLUN LUN capacity MetaLUNs provide the largest capacity of all LUN types.  Through a combination of striping and concatenating FLARE LUNs, very large metaLUNs can be constructed. It is easily possible to create LUNs of Petabyte capacities by using metaLUNs.   For example, assuming the maximum number of drives in a RAID group (16), and the maximum number of component LUNs that can make-up a metaLUN (512), the largest MetaLUN that can  be provisioned drive-wise could contain 8192 drives (16 drives * 512 component LUNs).  This value exceeds the capacity of the largest VNX storage system the VNX7500, which can accommodate 1000 drives. Cheers! Geraldo.

Hi Matthieu Can you inform me what version of SMI you have installed? Is there Solutions Enabler installed too? What error do you get when you try to access the System Director? The SMI provider uses namespace root/emc and for IBM ESS, root/ibm  root/cimv2 (namespaces are case sensitive) If you name as root/LsiArray13, that could be your problem. If you upgrade the SMI and did not remove existing Solutions Enabler prior the install (if you have Solutions Enabler) tou're going to have issues with namespace. Please let me know versions, errors etc. Cheers! Geraldo.

Hi Serdark! Thanks for using EMC's Forum. Try the procedure below and let us know the outcome! "Why can't I clear a Navisphere or Unisphere alert?" Only certain alerts are allowed to be dismissed because once a specific alert is dismissed, it is never shown to a customer again. Some alerts are deemed important enough to remind the customer of them and may fall into the non-dismissible category. Note: Engineering mode will not help as there is no "back-door" method to dismiss a non-dismissible alert. In the case of the "no available host spares" message, this was a new installation and configuration.  There were initially no hot spares configured on the array, which is contrary to best practices.  FLARE code Release 26 and later have a new alerts feature that will generate an alert if there is a configuration that is not recommended or does not follow best practices. The iSCSI alert cannot be dismissed because you need to set the IP addresses for the iSCSI ports even if you are not going to be using them. The default IP address for all iSCSI ports as shipped from the factory is 0.0.0.0 and if these ports are ever connected to a network, errors on the array and on the network will be generated.    For detailed information about alerts please use  Navisphere/Unisphere Help.    For Navisphere follow the path  Help > Help Topics > Managing Storage Systems > Managing Alerts > Resolving Alerts.                                                                        For Unisphere follow the path Support > Unisphere Help > Managing Block Based Systems > Managing Storage Systems > Managing Alerts > Resolve Alerts. Go to the View menu and deselect Alerts. This selection will persist for subsequent Navisphere sessions so the Alerts window will not pop-up automatically at the next time login. You can then look at the number of alerts shown in the upper right corner of Navisphere to determine whether any new alerts must be reviewed. In the case of a new installation with no hot spares configured, once a hot spare on the array was configured, the alert cleared itself. In the case of ISCSI alerts, if you have no plans to use iSCSI, set the addresses to 172.16.x.x or 10.x.x.x. Do not use 192.168.x.x. Cheers! Geraldo (Mediator)

Hi Doubleroll We thank you for using EMC's Forum! Please follow the procedure bellow and let us know the outcome! Ensure that the target LUN has been presented to the DR host. Perform the following steps: Before you install SRM, test the Replica LUN on the DR side.   'Enable Image Access' on the CG and make sure your ESX host can see the target LUN.         If it cannot see the LUN in question, perform the following corrective actions:  Put the LUN into the Navisphere storage group for the DR host.  Put the LUN into the Navisphere storage group for the RPAs.  Rescan the ESX HBAs (and VMFS for non-raw devices).
